Q:How big is the butterfly valve with a diameter of 80?
With the 80 caliber butterfly valve.Also known as butterfly valve, control valve has a simple structure, can be used for low pressure pipeline valve switching control is closed parts (disc or disc) is a disk, around the valve axis to achieve the opening and closing a valve, the valve can be used to control the flow of air, water, steam steam, all kinds of corrosive medium, mud, oil, metals and radioactive liquid media and other types of fluid.
Q:How to calculate the size of the manual butterfly valve?
I don't know what size you mean, and what about DN in diameter, such as DN125, which means 125 cm in diameter
Q:Butterfly valve is the control valve?
The flow characteristics of butterfly valves can be approximately equal percentage characteristics, with the positioner can do adjust, is mainly used in large caliber, straight stroke control valve more than 200 volume weight will be great, it suggests using the butterfly valve.
Q:How do hydraulic butterfly valves work?
3. butterfly valve hydraulic drive device structureThe valve hydraulic device is mounted on the valve drive shaft. The driving shaft of the valve is fixed with a transmission spline, and the crank (with an outer spline) is sleeved on the driving shaft. When the hydraulic system works normally, through the gear sleeve, the transmission spline is connected with the crank. Thus, the hydraulic cylinder drives the crank, and the spline on the crank passes the torque to the transmission spline by means of a gear sleeve. Because the driving spline is fixed on the driving shaft, the driving shaft rotates and drives the valve plate to start and close. A section of optical axis is arranged at the end of the driving shaft and is inserted into the end of the manual shaft (matched with the clearance of H11/ H11), and the function is that the manual shaft is concentric with the main drive shaft. In normal operation, the optical axis rotates with the drive shaft, but the manual device does not move. When the hydraulic operation is performed manually or manually from the hydraulic unit, a * * * conversion is required. The utility model is composed of a nut, a hand wheel, a screw rod, a support frame and a shifting device. When the utility model is switched, the hand wheel is rotated and driven by the screw rod to move. A guide rod is arranged on the bracket to make the shift and translation stable.
Q:Three eccentric hard sealing butterfly valve, why not fit in the end of the pipe?
The sealing ring will hold up. It does not fit in with the flange end of the pipeline, this addition is the most common and convenient pipeline after purge and easily add pipeline.
Q:How many kinds of butterfly valves are there?
What's the score?There are central butterfly valve, double eccentric butterfly valve, three eccentric butterfly valveAnd according to the materialAnd according to the way of connection
Q:Why do you need two butterfly valves in the water well?
Check the water gauge and check valve on both sides to facilitate the maintenance and replacement of water meter and check valve.
Q:Does the wet alarm valve group need to install the signal butterfly valve?
The wet alarm valve group shall be equipped with signal butterfly valve.The signal butterfly valve is generally installed in two parts: floor level, dry pipe, flow indicator front end, trunk pipe, wet alarm valve, front end.Floor level pipe installation is a function of the signal valve, when the floor spraying system needs repair, close the valve, open the end of the floor drain, emptying the water in the spray system, maintenance;
Q:What does "C" in D971F-16C DN450 RF mean for electric butterfly valves?
Valve carbon steel -16c body 316 stainless steel -16r
Q:Fire signal butterfly valve what role?
Signal butterfly valve should be human action monitoring alarm, once closed, that is, to the system alarmYou ask the two time, I answer two times, you give two points
